COVID-19 Roundtable: Prophylaxis for the Immunocompromised

For the immunocompromised there is limited efficacy to vaccines. In a mid-sized study published in the journal, Clinical Infectious Diseases, investigators found decreased COVID-19 vaccination seropositivity amongst immunocompromised populations vs nonimmunocompromised healthcare workers (HCWs). “Compared with HCW (92.4% seropositive), seropositivity was lower among participants with SOT (30.7%), hematological malignancies (50.0%), autoimmune conditions (79.1%), solid tumors […]

Ceftolozane Tazobactam Linked to Increased Clinical Success in Pneumonia

The CACTUS study found a 10% improvement in clinical success with ceftolozane tazobactam (CT), which was linked to a 1.5-fold increased chance of clinical success. After adjusting for residual differences between the treatment arms, the likelihood of success was nearly twice as high with CT. Despite these findings, mortality rates were similar between the two […]
